1. What is a BTU to kW Calculator?

Definition: This calculator converts power measurements from British Thermal Units per hour (BTU/h) to kilowatts (kW).

Purpose: It helps HVAC professionals, engineers, and energy specialists convert between these common power units.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P_{kW} \) — Power in kilowatts (kW)
• \( Q_{btu} \) — Power in British Thermal Units per hour (BTU/h)

Explanation: 1 kilowatt is exactly equal to 3412 BTU/h, based on the International System of Units conversion.

3. Importance of Power Unit Conversion

Details: Accurate conversion between BTU/h and kW is essential for equipment sizing, energy calculations, and comparing specifications from different regions.

4. Using the Calculator

Tips: Simply enter the BTU/h value you want to convert. The result will show the equivalent power in kilowatts.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 3412?
A: This is the exact conversion factor defined by the International System of Units (1 kW = 3412.142 BTU/h).

Q2: When would I need to convert BTU/h to kW?
A: Common applications include HVAC system specifications, generator ratings, and comparing equipment from different manufacturers.

Q3: How precise is this conversion?
A: The conversion is mathematically exact, though practical applications may round to 2-4 decimal places.

Q4: Can I convert kW back to BTU/h?
A: Yes, simply multiply kW by 3412 to get BTU/h.

Q5: What's a typical BTU/h rating for home air conditioners?
A: Residential units typically range from 5,000 BTU/h (1.5 kW) to 36,000 BTU/h (10.5 kW) for central systems.
